SAN DIEGO -- Derek Norris hasn't heard anything concrete.
But he has heard the rumors. And given what the San Diego Padres have done the past couple of weeks, he knows anything is possible with general manager A.J. Preller.
In the last week alone, Preller has traded four key members of the Padres contingent -- outfielders Matt Kemp and Melvin Upton Jr. and starting pitchers Andrew Cashner and Colin Rea. Earlier, Preller traded starting pitchers James Shields and Drew Pomeranz and James Shields and closer Fernando Rodney.
